Læringsmål

The students are introduced to the field of powder technology, and its importance for the process industry. Particulate solids represent 50 – 80 % of materials used or produced by typical large process industrial companies, as well as metal, mineral, food, pharmaceutical and other industries. In spite of this, powders are poorly described and understood, and few universities and colleges are offering this subject as part of MSc studies. The students following this course should develop an understanding of the basic concepts of powder technology, and should avoid the obvious mistakes often seen in industry when it comes to equipment for handling, storing and transporting, or for other processes where particulate solids are involved.
